SIGHT FOR FIREARMS.

SPECIFICATION forming part of Letters Patent No. 732,075, dated J' une 30, 1903. Application iiled January 20, 1903. Serial No. 139,730. (No model.)

To all whom it may concern,.-

Be {it known that I, LEwIs L. HEPEUEN, a citizen of the United States, residing at New Haven, in the county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Sights for Firearms, of which the following is a full, clear, and eXact description.

My invention relates to firearms, and particularly to sights therefor.

Among the objects of my invention are to provide a sight which is easily and accurately adjustable to enable the user to allow for the proper trajectory for varying distances. The mechanical construction is advantageous in its simplicity and durability and in the fact that when once set it cannot be disturbed in any ordinary use of the gun.

Figure 1 is a side elevation of the receiver portion of a gun fitted with my improved sight. Fig. 2 is aperspective view of the sight construction detached from the gun. Fig. 3 is a view of the under side of the sight. Fig. 4 is a longitudinal sectional view. Fig. 5 is a plan view with the open sight in use.

A represents the receiver of a gun, upon which the rear sight is mounted. Of course there is the usual bead or sight atthe forward end of the barrel to coperate with the adjustable rear sight; but my invention relates to the rear-sight member only.

The rear'sight comprises a frame having a base B with cheek-pieces C C and a plate D hinged at D', so that the rear end of said plate may be elevated or depressed. The rear end of this plate'carries the sight member. In the particular form shown the sight proper is either a peep-sight E or the open sight E', either of which may be thrown into operative position. In Figs. l, 2, 3, and 4 lthe peep sight is shown in the operative position ready for use, whereas in Fig. 5 the peep-sight is -swung back, (the sight proper being pivoted at E2,) so as to cause the open sight to be in the operative position. A spring E2, carried bythe plate D,rmay bear against iiattened portions on the swinging sight member, so as to hold either the peepsight or the open sight properly in place.

The screw E4 may be employed to hold the spring Es and to give it the proper tension.

The base-plateB may be secured to the receiver or frame A in any convenient manner-for example, by a screw or screws F F.

D2 is an extension or spur from the edge of plate D. The spur moves up and down in the slot or recess C' in the cheek-piece C when the sight-plate D is similarly moved. The wall at the rear of the slot C' is notched, and the adjacent edge of the projection or spur D2 is sharpened to fit into said notches, so that the plate D will be held at any desired angle relatively to the base B and so that the sight member will be correspondingly in any one of the notches in the wall at the I rear of the recess C. Vhen the sight is properly adjusted, a spring G presses the plate rearwardly against the notched edge of the recess C. The spring G may be placed in a pocket formed between the pivot D' and a shoulder VD3 on the plate D, the space between the hooked or bent end of the plate D and the spring G forming a pocket for receiving the pivot-pin D'. This method of connecting the plate so that it will be longitudinally movable and yet so that it will be forced rearwardly under all normal conditions is best seen in Figs. 3 and 4. The cheek-pieces C C serve to steady the platev D to insure the proper alinement of the sights E E'.

The sight may be quickly, easily, and accurately adjusted by reason of the fact that the lingers of thehand may grasp the receiverl and the thumb of the same hand be employed to press the plate forwardly to free the locking projection or spur D2, whereupon the sight may be elevated or depressed to any desired position, it being necessary to employ merely one hand to adjust the saine. The position and operation of the parts are such that the recoil due to discharge will not disturb or affect the adjustment in any way.

What I claim as my invention is- 1. A sight for rearms comprising a frame, a plate hinged thereto, a sight carried by said plate, means to permit the adjusting the plate to allow the sight to be elevated or depressed, comprising a projection or lockingspur ou said plate, a bearing on said frame to the rear of said spur to receive the thrust of the same and hold the sight end of the plate at the desired elevation and means for yieldingly pressing said plate rearwardly to produce said thrust.

2. A sight for firearms comprising a frame, a plate hinged thereto, a sight carried by said plate, means to permit the adjusting the plate to allow the sight to be elevated or depressed, comprising a projection or lockingspur on said plate, a bearing on said frame to the rear of said spur to receive the thrust of the same and hold the sight end of the plate at the desired elevation and means for yieldingly pressing said plate rearwardly to produce said thrust, said sight proper being pivotally connected vto the rear end of said plate.

3. A sight for firearms comprising a frame,

a plate hinged thereto, asight carried by said plate, means to permit the adjusting the plate to allow the sight to be elevated or depressed, comprising a projection or lockingspur on said plate, a bearing ou said frame to the rear of said spur to receive the thrust of the same and hold the sight end of the plate at the desired elevation and means for yieldingly pressing said plate rearwardly to produce said thrust, and a sight including an open sight and a peep-sight hinged to the rear end of the frame.

, 4. In a sight for rearms, aframe, a pivot supported thereby, a plate engaging said pivot and having a sliding movement relatively to the frame, a spring for normally pressing said` plate rearwardly, a projection or locking-spur carried by the plate toward its free end, a slot in said frame to receive said projection or spur and to permit the free end of said plate to be raised or lowered, a notched shoulder constituting a bearing adjacent to said projection and at the rear thereof, the sight proper being located at or near the rear end of said plate.
